Looking at how intact this ac is, relatively, I'm surprised no one at all survived.
In this crash in 2010 of an ec 130 it spun from a 220ft hover to the beach below in 6 seconds.
No fire, latest Eurocopter seats, the rear cabin intact, the front windscreen taken out by the rotors, all but one still strapped in.
Yet 4 of 5 occupants were killed on impact. Vertical impact of between 14G-20G.
